Shuddering and vibration in a 2014 Nissan X-Trail

If you mean shuddering and vibration when you take off from rest, then you’re possibly experiencing the same problem that many owners of this model Nissan have already reported. The problem is caused by wear in the CVT transmission which is allowing the steel drive belt to slip. As the belt slips and grips and then slips again, the driver experiences less-than-smooth acceleration.

The safety recalls (which were actually technical service bulletins) you’re referring to all occurred within the North American market and haven’t been extended to Australian X-Trails (that I know of). Unfortunately, US consumer law is quite different from ours and consumers have very different rights and obligations.

It would be worth having the car assessed and then approaching Nissan Australia’s customer service department to see if there’s any help on offer. But given the age of the vehicle, I wouldn’t be holding my breath. That said, I totally understand your point of view, and 11 years is probably not a suitable lifespan for a modern automatic transmission, given we’ve been making cars for more than 130 years, and Nissan (in one form or another) for the last 90 of those.
